"Tutorials in Physics: Quantum Mechanic" is a set of curricular materials for supplementing upperdivision quantum mechanics instruction, developed by the physics education group at the University of Washington. We describe the development of a sequence of three tutorials that focused on quantum measurements and time dependence. This…

This study investigated the effects of two different accountability scoring mechanisms (ASMs), which were used during the peer instruction (PI) process, on preservice middle school mathematics teachers' (PSTs) achievements in statistics and probability. In the spring semester of 2016-2017 academic year, 46 third-year PSTs, who had been attending a…

This pilot qualitative study explored K-8 pre-service teachers' (PSTs') learning experience in a Statistics and Probability course and their ability to make connections between mathematics and their everyday lives when given opportunities to investigate mathematics through a social issue. Data from student surveys, assessments, and written…

Collegiate athletes experience mental health concerns at similar rates to non-athlete students, however, the student-athlete population underutilizes professional mental health help with only 10% of those in need seeking services. Criticisms of the extant research on student-athlete mental health help-seeking include studies that lack theoretical…

In the early 90's, the United States reformed its welfare system through state waivers and the Temporary Assistance for Needy Families program. These changes altered family resources and potential investments for childhood human capital, which in turn could affect later adult outcomes. Using data from the Panel Study of Income Dynamics, I examine…

We study the effects of learning intensity and duration of high school on students' motivation, abilities and achievements at university. The empirical analysis is based on primary panel data from an education reform in the German state of Saxony-Anhalt that reduced university preparatory schooling from 13 to 12 years but left the curriculum…

A cross-national comparison between Italy and Spain was conducted on probabilistic reasoning performance presented in verbal-numerical and graphical-pictorial formats. This study investigated the similarities and differences in Psychology undergraduates in these two countries (Italy n=290; Spain n=130) and attempted to identify aspects that might…

There is growing pressure to make efficacy experiments more useful. This requires attending to the twin goals of generalizing experimental results to those schools that will use the results and testing the intervention's theory of action. We show how electronic records, created naturally during the daily operation of technology-based…

Mental health influences several major life outcomes. School-based treatment for mental health issues is the most effective intervention to support individuals with these problems. However, treatment availability and perceptions of mental health vary widely by country and their effects on the delivery and effectiveness of school-based mental…

The purpose of this study was to examine current overweight and obesity prevalence rates among US youth (aged 10-17 years) with and without autism spectrum disorder, based on the 2016 National Survey of Children's Health. Analyses of weight status, derived from parent-reported height and weight measures, were conducted for a weighted sample of…

Understanding large-scale patterns in student course enrollment is a problem of great interest to university administrators and educational researchers. Yet important decisions are often made without a good quantitative framework of the process underlying student choices. We propose a probabilistic approach to modelling course enrollment…

According to the most recent data available from the nationally-representative Survey of Income and Program Participation (SIPP), as of 2011, 38.4% of children lived in households reporting at least one form of material hardship, such as food insecurity, inability to pay essential household bills, inability to access medical care due to cost, or…

We examine the long-run impacts of having a same-race teacher. First, we leverage data from the Tennessee STAR class-size experiment to show that black students randomly assigned to a black teacher in grades K-3 are 5 percentage points (7%) more likely to graduate from high school and 4 percentage points (13%) more likely to enroll in college than…

Whether students are beginning their study of probability or are well into it, distinctions between complementary sets and mutually exclusive sets can be confusing. Cathy Schloemer writes in this article that for years she used typical classroom examples but was not happy with the student engagement or the level of understanding they produced.…

The purpose of this article is to develop a statistical model that best explains variability in the number of school days suspended. Number of school days suspended is a count variable that may be zero-inflated and overdispersed relative to a Poisson model. Four models were examined: Poisson, negative binomial, Poisson hurdle, and negative…
